Abstract
A web gauging system and methods of using the web gauging system are described. The web gauging system includes a supercontinuum Laser providing a light beam. A beam expander is configured to expand the light beam and provide an expanded beam to a sample illumination area. A detector unit configured to detect a sample light from the illumination area. A moving web can be placed in the illumination area, where the web gauging system measures parameters of the web.
Claims17
A web gauging system comprising:
- a supercontinuum Laser providing a light beam;
- a beam expander configured to expand and collimate the light beam and provide an expanded beam having approximately the width of a web to an illumination area;
- and
- a detector unit comprising a plurality of flipper mirrors each associated with a channel of the expanded beam, the flipper mirrors configured to sequentially pass a sample light from the channels to a detector.
